American Horror Story: Asylum is well into filming, but it has been announced that one actor from the first season is making a return. Ryan Murphy took to his Twitter account to announce that Dylan McDermott is back: "So thrilled to announce Dylan McDermott is returning to American Horror Story!"

Like most of the casting news, who he'll be playing and how he fits into the new story is a mystery. Based on the time of the announcement, we're guessing that it will be a cameo role toward the end of the season, but anything is possible. The first episode of American Horror Story: Asylum got the new season off to a good start last night with 3.85 million viewers, setting a new record for the anthology horror series. A total of 13 episodes are planned.

American Horror Story: Asylum features a brand new story set at an institution for the criminally insane during the 1960′s. Adam Levine, Chloe Sevigny, James Cromwell, Ian McShane, Lizzie Brocheré, Jenna Dewan, Clea Duvall, Franka Potente, Mark Margolis, Britne Oldford, Mark Consuelos and Joseph Fiennes make up the new cast, with Season 1 actors Jessica Lange, Frances Conroy, Zachary Quinto, Sarah Paulson, Even Peters, Eric Stonestreet, and Lily Rabe all returning as new characters.
